I own a Panasonic Lumix G85 camera that came with a 12-60mm F3.5-5.6 lens. I really like both the camera and the lens — they're compact and the lens is excellent. Since I occasionally shoot outdoor shots and videos, I ordered the K&F Concept UV filter for those situations and to protect my lens. The filter arrived quickly and out of the box I received the UV filter, a lens cap and a lanyard. Installing it on my camera's lens was very easy and I can already see an improvement in my photos and videos. Overall, I think this is a must-have accessory for the G85 with the kit lens and I highly recommend it.

Purchased to capture Full HD videos and images of trichomes to ensure a perfect tomato crop. It's super easy to connect to my phone or PC. Image quality is superb and focus is extremely smooth. I've had it here and there for a few weeks from the first charge so I'd say the battery is good too. Would definitely recommend.

Very good value set of filters. Ideal for for my Panasonic FZ1000 camera. The ND filter is especially useful for video as the camera doesn’t have one built-in. Recommended.

I have owned the K&F Concept Dual for more than 4 months now and would like to briefly share my experience.
First of all, I am still convinced of the dashcam! Overall, it delivers a good image, even very good images during the day, although it must of course be said that this model also does not have autofocus and therefore does not focus infinitely. Unfortunately, you can no longer read license plates or signs at night, but almost all dash cams in this price range have this problem. If an accident occurs, the video can also be used to reconstruct the accident at night.
I only use the front camera. It's a shame that you can use both cameras at the same time, but only in Full HD mode. For example, if you want to operate the front camera at 60 FPS, you inevitably have to leave the rear camera switched off. The processor is probably unable to process the data. If you set a resolution higher than Full HD, I personally don't see any advantage in the image.

The motion mode works very well. I've had to brake hard several times and the camera reliably saved the current video. If you want, you can save the video yourself at the touch of a button.

Works great with my Panasonic S5 full frame camera. Very good fit and finish and fits well on the camera body and M42 Pentax lens. Very satisfied!

the lens cap fits very well on the object of my Panasonic Limus camera (52 mm). The delivery was prompt. Item and delivery were perfect. Since a 2nd cover is part of it, you also have a reserve. I can only recommend.

I ordered this adapter to continue using some old Nikon lenses with a manual aperture on my Panasonic camera. It fits very precisely, nothing wobbles or jams. I also have a very good Novoflex adapter but this one is easier to fit.

The filters fit my Panasonic camera perfectly. They make a very well made and durable impression. I am sure that with careful use and proper care they will serve me well and for a long time.
I think this filter set is a good buy and value for money.
